Last time we spoke about the first battle of Changsha. Japanese forces under General Okamura Yasuji, including the 6th, 13th, and 33rd Divisions, launched a multi-pronged offensive, crossing the Xin Qiang River and capturing Yingtian amid brutal fighting. Chinese defenses, commanded by Xue Yue in the Ninth War Zone, employed gradual resistance strategies, with units like the 195th Division under Qin Yizhi holding key positions such as Bijia Mountain and Fulinpu, inflicting heavy losses. Battalion Commander Luo Wenlang recaptured Dongtang in a midnight assault, grieving his fallen brother amid Mid-Autumn moonlight. Chiang Kai-shek, from Chongqing, oversaw operations while hosting a festive banquet, buoyed by international support like U.S. loans. By October, Japanese advances stalled; Okamura ordered a retreat on October 2, exposed by a downed plane yielding critical documents. Chinese forces pursued, reclaiming lines by October 8, annihilating over half the invaders per Chiang's commendation.

In January 1939, the Japanese General Headquarters, responding to naval needs, ordered the 21st Corps to seize Hainan Island. The goal was to establish a base for air operations against southwestern China and to enforce blockade measures. Supported by the Japanese Navy, the Corps deployed the Taiwan Brigade, which landed at Haikou on February 10. After initial defeats, Chinese peace preservation units withdrew to the island's interior and conducted harassment operations. Japanese troops soon occupied northern counties including Qiongshan, Wenchang, Ding'an, Qionghai, and Chengmai, followed by the port of Yulin, which positioned them for southward advances toward Guangxi.

This invasion was part of a broader strategy to disrupt Chinese supply lines and secure a foothold in southern China. Although Chinese resistance on Hainan ultimately failed to repel the invaders, it highlighted the resilience that would define regional fighting.

After the costly Battle of Wuhan, the Sino-Japanese War reached a stalemate in central China, despite ongoing large-scale conflicts and Japanese strategic bombings that caused heavy casualties without breaking the deadlock. Politically, Japan's alignment with the Axis powers and the start of World War II in Western Europe led European nations to bolster ties with China. With major coastal ports under Japanese control, the Nationalist government's main overseas supply route became the Haiphong-Kunming railway in French Indochina, which transported four times more war materials in 1938 than in 1937, including heavy equipment purchased abroad.

The Hainan occupation negatively impacted Japan's war efforts, though diplomatic pressure on Britain and France proved ineffective. Meanwhile, the Imperial Japanese Navy proposed a southward advance: invading from Nanning to Longzhou County in Guangxi by sea to establish an airfield for strategic bombing. An April 15, 1939, Navy Department assessment deemed large-scale inland army operations challenging, recommending instead that the army and navy collaborate to occupy Shantou—the largest trading port on the South China coast—before pushing into Guangxi to seize Nanning and sever China's vital Indochina supply line.

In June, the Japanese General Staff's "Military Geography" emphasized that occupying Nanning would provide convenient transportation in all directions, reaching Guangdong, Hunan, Guizhou, and Yunnan. The Nanning-Lang Son road had become a major artery for Chiang Kai-shek's regime to connect with the southwest. To cut it off directly, Nanning must be captured first. Once occupied, heavy troops near Tokyo Bay would not be needed to achieve the operation's purpose. This idea gained considerable support both politically and tactically. The Army's northward policy had been defeated by the Soviet Union in the Battle of Khalkhin Gol in September 1939. Major General Tominaga Kyoji, the newly appointed head of the First Department of the General Staff, sought to avoid further embarrassments. Supporting the proposal involved transferring the 5th Division of the Kwantung Army, originally intended for Khalkhin Gol, to the south. This prevented front-line units from misjudging higher-ups' positions and allowed implementation without affecting existing troops.

In September, the European war broke out. The Japanese General Headquarters ordered the 21st Army to capture the vicinity of Nanning, cut off the international passage between Guangxi and Vietnam, and obtain a base for air operations in southwest China. Japan aimed to completely sever China's most important supply route. According to Japanese intelligence, the French Indochina line accounted for 85% of China's foreign aid in late 1939, with 12,500 tons transported in September alone.

On September 1, 1939, Germany attacked Poland; on September 3, Britain and France declared war on Germany, igniting World War II. Japan, eager to resolve the China issue and free up troops to seize Western colonies in Asia and the Pacific, stated through Prime Minister Nobuyuki Abe on September 4: "At the outbreak of the European war, the Empire will not intervene and has decided to focus on resolving the China Incident." In Nanjing, the China Expeditionary Army Headquarters was established, with General Nishio Hisazo as Commander-in-Chief and Lieutenant General Itagaki Seishiro as Chief of Staff, overseeing the North China Area Army, the 11th Army, the 13th Army, and the 21st Army.

On September 23, the Japanese General Headquarters issued an order to prepare for a swift response to the China Incident. On October 16, "Continental Order No. 375" directed the Commander-in-Chief of the China Expeditionary Army to swiftly cut off enemy supply routes from Nanning to Longzhou with a portion of the navy. Also on October 16, "Continental Order No. 582," a central Army-Navy agreement, aimed to cut off enemy routes along the Nanning-Longzhou line and strengthen naval air operations against the Yunnan-Vietnam Railway and the Burma Road. The operation was scheduled for mid-November. On October 19, Nishio Juzo issued orders for the Guangxi operation, involving the 5th Division, Taiwan Mixed Brigade, supporting units, the 5th Fleet (renamed the 2nd Expeditionary Fleet in mid-November), and the 3rd Combined Naval Air Group. Total strength: about 30,000 men, over 70 warships, 2 aircraft carriers, and about 100 aircraft. Tominaga Kyoji announced: "This is the last battle of the China Incident."

Politically, the Guangxi Army was a key pillar of the National Government after retreating to Sichuan. Attacking Guangxi could impact the Guangxi clique's stance on continuing the war. Cutting off the Nanning-Longzhou line would affect Vietnam-China transportation security and allow actions against French Indochina amid Europe's distractions. With tactical and political alignment, the plan was approved.

In September 1939, the Chinese repelled the Japanese attack on Changsha. In October, the National Government held the Second Nanyue Military Conference in Hengshan, summarizing the First Changsha Campaign and deciding on a new offensive. On October 29, Chiang Kai-shek announced: "Our future strategic application and the mentality of officers and soldiers must be completely transformed. We must start to turn defense into offense, turn stillness into movement, and actively take offensive measures." On November 5, after the meeting, intelligence indicated Japan's intention to invade the south. U.S. and British agencies reported the Japanese fleet gathering in Tokyo Bay, signaling an imminent operation against Nanning. Chiang flew from Hengshan to Guilin to arrange defenses.
